TLV320AIC3100 Codec Porting for the IMX8MP Custom Board

[Wobaffet]

Hello,

I am trying to port TLV320AIC3100 for a custom board with imx8mp MPU. I've problem when probing the device with the simple-card driver. Having an issue with the dai-link configuration. Can you detect the error on my configuration? It is based on this post. I have the below config for the DT.

/   {

Codec is probed when we moved back to 5.15 with the same configuration.

[Adi99]

Hi @Wobaffet 

its great to hear you codec is working

Can you share the full patch and debugg logs so we also verify our end.

[Wobaffet]

Hello, the codec is not working yet, we don't see any movements on the MCLK. Here is our latest configuration on a new issue.

Thanks!

We are not able listen music, but some buss sound we can listen.

Guide me if in any changes required are any necessary things to check.

Hello MJD, sorry for the late response. Can you please share the

cat /sys/kernel/debug/devices_deferred output.

Thanks!

I am i attaching the dts file

[Wobaffet]

Hello,

We have the same problem and unfortunately, we don't have any solution yet. However, we've also asked TI about this matter maybe their suggestions can help you.

Best Regards.

Hello @Wobaffet 
I had an doubt with my dts file attached in the previous message, pls clarify wither the @i2c3 bus. 
voltage supply parameters given to the codec are correct? 

[Wobaffet]

They seem to be okay, also you can manually copy the ko for the codec driver assuming tlv320aic31xx.ko is not included in your image, and then you can dynamically debug the issues if there exists one. As I recall there should be debug statements within the tlv320aic31xx driver.

[Wobaffet]

Hello, @MJD  unfortunately no luck. Are you using the same MPU?

[MJD]

hi @Wobaffet 
Actually i do not see tlv320aic3101 chip got probed, can you please guide me to fix, i have attached dt file. 

[MJD]

Yes. with tlv320aci3101 chip

[MJD]

hi @Wobaffet 
Did you got the solution, if so please can share me the DT file.. 

[Adi99]

Hi @Wobaffet 

you got any solutions? i am also using same codec chip for my custom board.

[Wobaffet]

Hello Thomas,

Unfortunately I couldn't find any solution. TI suggested this working configuration. But also did not worked for me. Maybe you can also check it could work out for you. If so can you let me know?

Hi @Wobaffet 

What is the problem you are facing?

chip is not probed ? OR 

issue you are facing related audio-card?

[Wobaffet]

Well, tlv320aic31xx i2c driver is probed successfully but aic31xx_codec_probe function is not being called, also SAI peripheral and audio-card driver is deferred. I've tried both simple-audio card driver and fsl-asoc-card driver, the situation is the same for both audio-card drivers.

[Adi99]

Yes exactly same issue is i am facing.

i2c chip is probed but the issue in  simple-audio card driver and fsl-asoc-card driver . 

also in dts file its gives me below error:

/sound-tlv320aic31xx: Reference to non-existent node or label "codec_tlv"

codec_tlv node is already available in dts file.

[Wobaffet]

For the non-existent problem, have you checked the generated dtb if the node is created or not?

And if you can find a solution regarding the audio card driver could you share the solution?

Thank you in advance! 

Best Regards.

Hello, I hope you are doing well.

We do not have a specific device tree configuration for TLV320AIC3100 codec but, we have a device tree example from the EVK board and also some documentation that you could use as a reference for your design.

simple-card.yaml 

tlv320aic31xx.txt 

fsl-asoc-card.txt 

imx8mp-evk.dts 

What it the issue that you are presenting with dai-link configuration?

Best regards.
